ELEVATOR FOR BALING-PRESSES.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed December-3, 1907. Serial No. 404,954.

T 0 all whom it may concern} Be it known that 1, WILLIAM PARKER, a citizen of the United States, residing at Ellensburg, in the county of Kittitas and State of Vashington, have invented a new and useful Elevator for Baling-Presses, of which the following is a specification.

The invention relates to an elevator for baling presses.

The object of the present invention is to provide a simple and comparatively inexpensive attachment for baling presses and analogous compresses, adapted to enable abale of hay, cotton, or other material as it leaves the press to be readily handled and easily placed upon a pile.

A further object of the invention is to provide an elevator attachment of this character, adaptedto be compactly arranged upon the rear portion of a baling press, when the latter is being transferred from one place to another.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a side elevation of an elevator, constructed in accord ance with this invention and shown applied to the rear portion of a baling press. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal sectional view. Fig. 4 is a transverse sectional view, taken substantially on the line :2cr of Fig. 3.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

The elevator has a frame composed of two sections 1 and 2, each provided with wooden side bars and having suitable connecting rods 3. The inner section 1, which is arranged horizontally when the elevator is in use, is hinged at its inner. or front end to the rear end of the frame 4 of a baling press by means of a transverse shaft 5, journaled in suitable.

bearings 6 and piercing the sides of the section 1 of the elevator frame. The bearing brackets 6, which are arranged beneath the frame of the baling press, are secured to the same by bolts, or other suitable fastening devices, and they project rearwardly from the baling press frame 4. The adjacent ends of the sections 1 and 2 of the elevator frame are connected together by hinges 7, and the end edges 8 are cut away at an angle of forty five degrees to permit the sections of the elevator to be arranged at right angles to each other, as illustrated in dotted lines in Fig. 1 of the drawings, for folding the elevator upon the frame of'the baling press. The leaves of the hinges 7 are secured to the lower edges of the sides of the sections of the frame of the elevator, and they may be of any preferred construction, as will be readily understood.

The elevator is equip ed with transverse dead and live rolls 9 an .10 and an endlessconveyor, comprising a pair of endless sprocket chains 11 and transversely disposed load carrying connecting angle bars 12. The angle bars, which are constructed of steel, are each composed of two flanges or wings, arranged at right angles to each other, one of the flanges or wings being rovided with projecting terminals secure sprocket chains, and the other flange or wing extending from the sprocket chains at right angles to the same. The rolls 9 and 10, which are arranged at intervals, are mounted on transverse shafts 13, and the endless sprocket chains are arranged on sprocket wheels 14 and 15. The sprocket wheels 14 are keyed, or otherwise secured to the end shaft 5, and the other sprocket wheels 15, which are located at the rear end of the elevator and at a point intermediate of the ends thereof, are mounted on the shafts of the live rolls 10, which are shorter than the said rolls 9, sufficient s ace being provided at each end of the rol s 10 for the sprocket wheels. The live rolls 10, which are equipped with the sprocket wheels, are continuously rotated when the elevator is in operation.

The inner transverse shaft 5 carries a pulley 16, which receives a drive belt 17, eX-

tending rearward from the front portion of the baling press and located at one side thereof and having upper and lower flights or stretches arranged on idlers 18 and 19, but the means for operating the elevator may be arranged in any other suitable manner, as will be readily understood. The front section 1 is supported in a horizontal position by means of legs 20, pivoted at their upper ends to the outer faces of. the sides of the inner section of the elevator and adapted to be tothe vator thereof.

charging end thereof.

folded longitudinally of the inner section, when the latter is folded against the frame of the baling press. The rear or outer section of the elevator is adapted to be arranged at different angles or inclinations, and is Llesigned to be gradually raised. as the pile of bales increases in height, so that the bales will be discharged by the elevator upon the top of the pile. The rear inclined section of the elevator issupported by an adjusting device, composed of a pair of drums 21, mounted on a transverse shaft 22 and receiving wire cables 23, or other suitable flexible connections, which are secured'at their outer ends to the inclined section of the ele The transverse shaft 22 is journaled in suitable brackets upon the frame of the baling press at the top of the rear end thereof, as clearly shown in Figs. 1 and 3 of the drawings, and it is equipped with suitable ratchet mechanism for holding the shafts against retrograde rotation.

The ratchet mechanism preferably consists of a ratchet wheel 24 and a pawl 25, mounted in one of the bearings and engaging the ratchet wheel, which is keyed or otherwise secured to the shaft 22. The shaft 22 is also equipped with a crank handle 26 for enabling the adjusting means to be readily operated for raising or lowering the inclined section of the elevator.

The baling press is provided at its rear end with a bale-receiving platform 27, connected at its inner or front edge to the frame of the 35,

baling press at the bottom thereof by suitable hinges 29, and supported in a horizontal position by chains 30. The platform, which forms an extended support for the baling press, is adapted when folded to close the mouth of the same. The bale is transferred from the platform to the elevator,.and is engaged by the upwardly projecting portion of one of the transverse load-carrying connecting bars or members 12, and is conveyed along the elevator frame to the rear dis- The bale 31, illustrated in dotted lines in Fig. 3 of the draw ings, is supported by the transverse rolls, which rotate to enable the bale to readily pass over them. The positive rotary movement of the rolls having the sprocket gears assists in conveying the bales rearwardly, and any number of rollers may be provided -with such gears, which also support the up per stretches of the sprocket chains.

.The upper flights of the sprocket chains are maintained in engagement with the sprocket gears by means of idler sprocket wheels 32, located at the hinged ends of the sections of the elevator frame and mounted on adjustable plates or members 33, provided with slots 34 and secured to the sides of the sections by bolts 35, orother suitable fastening devices. By adjusting theplates or members, which carry the idler sprocket wheels, the endless chains may be varied in tension and made as tight or loose as desired. These idler sprockets prevent the chains from getting out of mesh with the sprocket gears through any adjustment of the inclined section. The inner section is provided adjacent to the inner end of the outer section with sprocket pinions 36, adapted to hold the lower flights or fingers of the sprocket chains out of engagement with the sections of the elevator frame.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with a baling press, of an elevator comprising a frame hinged to the rear end of the baling press and provided with a plurality of foldable sections, the inner sec tion being arranged horizontally in position to receive the bales from the baling press,.and a platform hinged to the baling press and foldable against the rear end thereof and ex tending outward therefrom over the horizontal section of the elevator.

2.
